Space Weather Prediction Center and the U.S. Air Force.
UPDATED 2015 October 29 0030 UTC .24 hr Summary… Solar activity was at low levels. Region 2436 (N08W74, Cao/beta) and Region 2437 (S18W62, Cro/beta) both produced low-level, C-class flares during the period. Region 2442 (N16E09, Cao/beta) and Region 2441 (N14E33, Dro/beta) exhibited small growth in the leader and trailer spots. A new cluster of sunspots became visible along the east limb near N09 late in the period as noted in SDO/HMI Intensitygrams. These sunspots are likely associated with the active region along and just beyond the east limb that produced some surging and small X-ray flares over the past two days. The sunspot group was assigned as NOAA SWPC Region 2443, but we are awaiting a first observatory report in order to properly classify the spot group. All other regions were mostly stable or in gradual decay. A disappearing filament near S20E20, erupted from the Sun around 28/1200 UTC as observed in SDO/AIA 304 imagery. An associated coronal mass ejection (CME) was noted in SOHO/LASCO C2 imagery starting at 28/1325 UTC. Analysis is ongoing to determine if there is an Earth-directed component. .Forecast… Solar activity is expected to be at low levels over the next three days (29-31 Oct), with a slight chance for M-class (R1-R2/Minor-Moderate) flares primarily due to the flare potential of Regions 2436, 2440, and newly assigned Region 2443.
